Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]
The distal veins are removed following the complete ablation of the proximal vein. This treatment is most commonly used for varicose veins off of the great saphenous vein, small saphenous vein, and pudendal veins. [60] Follow-up treatment to smaller branch varicose veins is often needed in the weeks or months after the initial procedure.
To place the filter, a catheter is guided into the IVC using fluoroscopic guidance, then the filter is pushed through the catheter and deployed into the desired location, usually just below the junction of the IVC and the lowest renal vein. [44] Review of prior cross-sectional imaging or a venogram of the IVC is performed before deploying the ...
People often experience adverse side effects from immunoglobulin infusions, including: swelling at the insertion site (common in SCIG) chills; headache; nausea (common in IVIG) fatigue (common in IVIG) muscle aches and pain, or joint pain; fever (common in IVIG and rare in SCIG) hives (rare) thrombotic events (rare)
Laser therapy uses a light beam that is pulsed onto the veins in order to seal them off, causing them to dissolve. These light-based treatments require adequate heating of the veins. These treatments can result in the destruction of sweat glands , and the risk increases with the number of treatments.
Vein stripping is a surgical procedure done under general or local anaesthetic to aid in the treatment of varicose veins and other manifestations of chronic venous disease. The vein "stripped" (pulled out from under the skin using minimal incisions) is usually the great saphenous vein. The surgery involves making incisions (usually the groin ...
Deep vein thrombosis may require thrombolysis if there is a significant risk of post-thrombotic syndrome. [42] Thrombolysis may be administered by intravenous catheter directly into the clot ("catheter-directed thrombolysis"); this requires a lower dose of the medication and may carry a lower bleeding risk but evidence for its benefit is limited.
The initial "shrinkage" is caused by spasm of the muscular layer of the vein wall. The sclerosing solution damages the vein wall, causing inflammation and gradual scarring ("sclerosis") over the following weeks. The sclerosis is caused by an increase in fibroblasts in the cell wall which causes contraction of the vein.
